Abstract
BACKGROUND: The aim of this study was to investigate dentists` knowledge, attitudes and factors regarding the conservative approach in the management of deep caries lesions (DCLs) in teeth with reversible pulpitis. MATERIAL AND METHODS: 187 dentists were contacted directly or by mail, and 125 (67%) were finally included in the study. Dentists were requested to answer an open/discursive questionnaire about the routine approach to the diagnosis and treatment of DCLs, including knowledge-related attitudinal items. RESULTS: Total caries excavation was the preferred treatment option for more than 80% of dentists in case of DCL with reversible pulpitis. Only a small percentage (8%) chose partial caries removal, leaving some carious dentin close to the pulp to avoid pulp exposure. More than a half (51%) of respondents considered that cariogenic microorganisms must be removed or caries would progress. Dentists teaching at the University strongly disagreed with this statement (OR = 4.6; 95% C.I. = 1.3 - 15.8; p = 0.017). Good clinical result was the most chosen reason (83%) to choose a specific treatment. Patient's oral health (84%) and patient's age (70%) were the two patient-related factors most taken into account for the choice of treatment. CONCLUSIONS: Total caries excavation is still the most frequently chosen treatment in teeth with DCL and reversible pulpitis. The joint assessment of the answers given by respondents allows to conclude that the new knowledge and concepts about caries lesions and the more conservative approach to DCLs have not still been incorporated by dentists into their usual clinical practice.
